Sectionally subdivided bilateral sticker tape roll

ABSTRACT

A supply tape roll for stickers coated on both sides with pressure sensitive adhesive is composed of a carrier tape, coated on both sides with a repellent or inhibitor for adhesive, and a sticker tape coated on both sides with a pressure sensitive adhesive and subdivided into sticker segments by a pattern of transverse linear cuts forming one or more narrow connecting strips between sticker segments, which allow a sticker to be pulled away from the succeeding sticker for a distance before it is torn off. The sticker tape and carrier tape are rolled up together to form a supply roll particularly adapted for use in dispensing devices.

4 Claims, 5 Drawing Figures SECTIONALLY SUBDIVIDED BILATERAL STICKER TAPE ROLL This invention relates to a tape composed of severable segments, coated on both sides with a pressure sensitive adhesive, which are utilized to fasten together opposed surfaces of paper, plastic or other sheets, as for fastening photographs or documents on a backing, on an album leaf, on another document, or the like.

Rolls of tape are known in which a sequence of completely separated two-way sticker segments are disposed on a carrier tape having a coating for rejecting or mitigating adhesion. In these rolls the upper adhesive coating layer of each sticker is covered by a patch stamped into the same shape as the sticker and coated, like the working side of the carrier tape, with an antiadhesive. Such tapes have the disadvantage that the stickers do not allow themselves to be dispensed in fully usable condition from a dispensing device.

It is also known to place a tape coated with adhesive on both sides next to a carrier tape coated on both sides with a repellent or inhibitor for adhesives and to roll the two together. Such a tape can be used in segments only by cutting it up after pulling off the covering tape. Dispenser devices for utilizing a tape of this type are provided with a cutting mechanism which requires expensive technical effort to produce as well as to design it for consistently successful performance.

This invention is directed to the problem of providing a roll of tape subdivided into severable segments coated on both sides with pressure sensitive adhesive which is capable of use without expensive mechanical contrivances and without excessive hand work.

The solution of the problem is found in a tape of connected but easily separable sticker segments arranged on a carrier tape that is coated on both sides with a repellent or inhibitor for adhesives. With this kind of tape structure the result is obtained that a segment pulled off from the carrier tape draws the following segment after it up to the point of tearing away, whereby the situation is avoided in which the following segment of the tape roll remains stuck to the underside of the carrier tape. The tape with connected but readily separable segments lends itself particularly well to use in simple dispensing devices in which the composite tape is pulled off the supply roll and the carrier tape is pulled around a reversing guide vane, whereby the segment reaching this position lifts off the carrier tape as the latter is folded back on itself. By a slight pull this segment is then torn away from the following one that still more or less completely adheres to the carrier tape.

When the composite tape is pulled off the roll, because of circumstance that the sticker segments are as yet not fully separated from each other but are merely readily separable but still connected together, the leading segment always pulls the following one along, so that the latter cannot remain stuck on the underside of the carrier tape.

The sticker segments of the tape are joined in succession by weakened portions, such as are provided by transverse indentations or cuts. Preferably the segments are defined by transverse patterns of cut lines between successive segments, each such transverse pattern having two or more out lines alternately or otherwise displaced one from the other, each cut extending only part way across the tape. The relative displacement of the cut lines forms one or more (as the case may be) narrow connecting strips between the sticker segments. By this construction it results that after one segment is stripped off the carrier tape, the following segment at first continues to be pulled along by the connecting strip or strips that become extended until they eventually break off, severing the tape. The strips have the further significance that when the composite tape, consisting of carrier tape and the two-way sticker tape, is rolled up, the tensions arising in the two-way sticker tape are equalized by elongation at the strips connecting the segments.

The cut lines are preferably so designed that successive cuts are in partial parallel overlap and the sequence of cuts extends across the tape in such form that the strips can be made to extend substantially lengthwise of the tape, especially when there is a pulling load on the tape by which the strips have already been stretched. After being extended in that manner, the strips can easily be torn off because of the disposition of the fibers of the tape material under the circumstances.

It is generally sufficient to provide two cut lines, one extending from each edge partly across the width of the tape, displaced with respect to eachother and in parallel overlap in the middle, in which case only one connecting strip is formed. In particular cases, however, it has been found advantageous to arrange, over the total width of the tape, several cut lines alternately displaced, each extending over a portion of the width of the tape and sequentially in parallel overlap, whereby several connecting strips are formed. This arrangement is particularly advantageous in the case of wide tapes.

In the case of particular applications it is also useful to make the cut lines inflected or sinuous rather than straight.

For the further explanation of the invention reference is made to several illustrative embodiments set forth in the annexed drawing, in which:

FIG. 1 is a plan view of the tape;

FIG. 2 is a perspective diagramatic view of the tape during the pulling off of a sticker segment from the carrier tape as the latter is led around a guide vane;

FIG. 3 is a plan view of another form of tape embodying the invention;

FIG. 4 is a plan view of still further form of tape embodying the invention, and

FIG. 5 is a plan view of still another form of tape embodying the invention.

The tape 1 is composed of a base layer coated on both sides with pressure sensitive adhesive, subdivided into segments which are disposed on a carrier tape 3. The segments 2 are defined by cut lines 4 running transverse to the length of the tape, partly in overlap and alternately displaced relative to each other. By the displacement of cut lines 4, strips4 connecting segments 2 are fonned.

As may be seen in FIG. 2, the material of strips 5 is extended appreciably when a segment 2 is pulled mi from carrier tape 3, until the extensibility of the material of strips 5 is overcome and the strips tear.

As may be seen in FIGS. 1 and 2, the cut lines 4 can be arranged with such relative displacement and partial parallel overlap that two strips 5 are formed. In the case of narrow tapes (FIG. 3), however, two cut lines 4 will be enough, extending respectively from the edges across the width of the tape and running partly in parallel overlap, in which case only one strip 5 is formed.

As shown in FIG. 5, the cut lines 4 can also be provided in inflected form, the illustrated case showing a bend of the line where the overlap begins. As shown in FIG. 5, in the case of inflected cut lines, only the overlap portion needs to have relative displacement and the outer portions of the two cuts may be in alignment. In the case of relatively broad tapes (FIG. 4) a multiplicity of cut lines are provided in a pattern extending across the tape. The alternate displacement of these lines forms several strips (four in the illustrated case) between successive segments.
